JACKSON L. KAIL, OF CHICAGO, ILLNOIS.

Application filed 'March 3l, 1913.

To all whomI it may concern Be it known that l, JACKSON L. Kain, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful improvement in lindows, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification. y

This invention relates to an improved construction of window by which the .window is made in two parts so mounted in a window frame that one part counter-balances the other, the parts beine' so connected that they may be swung upon supporting levers 4so as to secure any desired degree of opening between the window sash and the casing. rllhe counter-balancing of the sashes is secured without the use of weights of any description outside of the sashes themselves, and furthermore, the sashes are so disposed in the window frame that when the window is closed the two sashes lie substantially in the same plane, thus presenting a continuous and practically unbroken surface to the weather, which adds much to the architectural effect of the structure.

l am aware that constructions have been employed in the past in which the two saslies are connected by levers so as to counter-balance each other, and l do not therefore, claim broadly as my invention this arrangement.

On the other hand my vinvent-ion consists in improved structural features by which the results described are secured, as well as a construction facilitating the use of iron or steel in the window frame and sashes for the construction of lire-proof windows.

ln carrying out my invention, the sashes and frame are so constructed that there are interlocking joints all around each sash, both with the window frame and the other sash, as a result of which weathertight joints are secured. When the sashes are movcdto their opened positions, they lie on the same side of the window frame, preferably he inside, thus differing radically `from those prior art structures wherein the sashes lie on opposite sides of the window frame `when the window is opened.

In one embodiment of my invention l provide means carried by the window fiame for guiding the lower end of each of the sashes.

The upper portion of the upper sash isA Specification of Letters Patent.

lever pivotally connected to the upper pory tion of the lower sash. The devices connecting the sashes are so conformed and disposed that as the upper portion of the lower sash is moved inwardly and upwardly, the

upper portion of the upper sash is automatically moved inward and downward.

ln another embodiment of my invention l provide means for connecting the window saslies whereby an operation of the sashes similar to the operation of the sashes of the first mentioned embodiments of lmy invention is accomplished without the .use of meshing pinions. In this second embodiment of my invention the desired Voperation of the sashes is secured by providing a novel arangeineiit of levers connecting the two sashes.

These and other features of the window of my invention are illustrated in the accompanying drawings and set forth in detail in the followingA descriptions.

In the drawings: Figure'l shows in inside elevation a window and frame constructed in accordance with my invention. Fig. 2 is a vertical sectional view taken through the parts shown in Fig. l along the line 2 2 of Fig. 1. Fig. 3 is a vertical sectional view taken through the parts shown in Fig. l along the line 3 3 thereof. Fig. 4 is a fragmentary sectional view taken on the line 4 4 of Fig. 8. Fig. 5 is a perspective view illustrating one of the pivoted guiding members for the lower sash. Fig. 6 is a fragmentary elevational view illus trating ho-w the lower sash is secured to the pivoted guiding members. Fig. 7 is a vertical sectional view illustrating a modified form of window embodying my invention; and Fig. 8 is a view similar to Fig. 7 illustrating the sashes so disposed that they are supported by the pivoted guiding members which normally serve to guide the lower portion of the lower sash. v

Similar reference numerals refer to similar parts throughout the several views.

At- 9 l have illustrated a rectangular window frame constructed of channels, as shown. Secured to the upper channel of each frame is a transverse bar 10, to which is secured an angle 11, as shown, the flange of the angle being turned toward the inside of the window trame. The side channels of the window frame are also provided with angles 12, which correspond to the angle 11 of the upper channel, these last mentioned angles being secured to bars 13, which cor.- respond to the bar 10, which supports the angle 11. The angles 11 and 13 are adapted to overlap suitable flanges carried by the window s'aslies, and so provide a weather tight joint.' Y

kDisposed within the window frame, are upper 4and lower sashes 14 and 15. When thesashes are in. the positions shown in Fig. 1^, ythe channels constituting the top and sides ofr the upper sash, overlap inturned flanges ofl the angles supported by the window frame. The lower flange of the upper sash overlaps the bar constituting the top oii'the lowersash. The flanges ot the angies constituting` the sides of the lower sash over/lap the' angles 12, as shown, and the lower portion ofthe lower sash is conformed as most clearly illustrated in Fig. 5, to iit over a bar 16, extending transverselv of the bottom channel o :ttlie window trame. Thus ijieather tight joints are had throughout, whenfthesashes are in their closed positions. l Pivotedto the side channels of the window 'iframe at either end of the bar 16, are guiding rods 17, each ot which is provided at its tree end with an aperture 18. Carried the side channels ofv the window frame the tops of'said channels. are brackets 19.v Disposed between each of the brackets 19 and itsv supportingchannel, is a pair of meshing pinions indicated-at 20 and 21, each of said pinions having one of its bearings in` one of the lbrackets 19 and its other bearing in its associated channel. Rigidly secured to each of the pinions 20 is a lever 22, which is also pivoted to the upper portion of, the upper sash 14. Rigidly secured to each of the pinions Q1 is a lever 23, which is also pivoted to the end of a bar 24, carried by the lower window sash 15. The bars 24 are preferably securedto the lower window sashes by means ot" screws 25-25, as illustrated. As clearly illustrated in Figs. 2 and 4, the'levers Q2 are spaced somewhat from the window in order that the levers 22 and 23 may pass each other when the sashes are moved to their opened positions,

l Carried by each of the vertical channels of tliewindow VJtrame, is a guiding strip 26, preferably secured in place by means of screws 27-27, as illustrated. Pins E28 carried by the lower endet the upper sash are adapted to ride behind the guiding strip 26 and Aso prevent the lower end or the upper sashfroin swinging away from thewindow trame when the sashes are moved to their eren. Positions- As mest clearly illustrated in Fig. 5, the

kscrews EO, extending from the inside of the lower window sash. The purpose oi"- these locking blocks is to retain the lower sash in engagement with the guide bars 17. YVhen ythe parts are in operative position, the guiding bars are placed in the positions shown in Fig. 5 and the locking blocks are turnedby turning screws upon which they are pivoted, until the oblique surfaces of the block engage the adjacent portions of the sash, and thel locking portions of the block project out over the strip 2,8 and engage the adj acent guidingbar 17. Continued turning ot the screws 30 locks the locking blocks rigidly in position.

At 31 l have illustrated a locking lever which serves to engage a plate 32, and so lock the sashes in theirnormal vertical positions, as clearly shown in Fig. 1. Then the saslies are to be moved to their open positions, the lockingl lever 31 is disengaged from the plate 32 and the upper portion of the lower sash grasped and pulled inwardly and upwardly. As the lower sash is moved inwardly andupwardly, the upper sash, by virtue of the lever connections above described, is moved inwardly and downwardly. It should be noted thartthe construction of the window above set forth is such that a metal construction may be had throughout, and that a weather proof exterior is presented to the weather when the sashes are moved to their closed position and locked.

t 33 have illustrated ahandle which may be used for moving the lower sash to its normal closed position or for moving the sashes to their opened positions after the upper portion of the lower sash has been moved inwardly an amount sufficient to bring the lever mechanism into play.

1n Figs. 7 and 8 I have 'illustrated a modiiied form of window construction wherein no pinions are used. In this form window, the upper portion of the upper sash illustrated at 40 is pivoted to levers 41, which are in turn pi'voted to the window frame at The levers 41 are provided with ears 43, of reduced cross-section, which are pivoted in the bifurcated ends of links 44, the other ends of which are pivoted to the short arms of levers 45, pivotally 1uounted upon studs 46, carried by the window frame. rllhe long arms of the levers 45 are pivotally connected to the upper portions ot the lower window sash, as illustrated. 1n this form of construction, the means for holding the lower portion of the lower sash in sliding engagement with the pivoted guide bars, illustrated at 47, is somewhat diderent than the means provided in connection with the forni of window illustrated in Figs. l to 6 inclusive. In this second 'form of window construction, the guide bars 47 are placed between blocks d8, and the side flanges of the lower window sash. vEivoted plates 49 carried by studs 50 on the inside of the lower sash, are then swung through apertures in the side lianges to lock the guide bars et? in position. The result accomplished by the form of window illustrated in Figs. 7 and S is in all respects the same as the result accomplished by the -form ot window illustrated in TFigs. 'l to 6 inclusive. In Fig. 8 I have shown the lower end of the upper sash supported by the guide bars d?, the apertures in the :tree end thereof being slipped over the pins which normally retain the lower end oi' the upper sash in sliding engagement with the window frame. It might be said that the sashes or" the. window construction illustrated in Figs. l to 6 inclusive may also be supported as are the sashes illustrated in Fig. 8.

While I have illustrated my invention in the particular embodiments herein shown and described, I do not wish to be limited to these particular constructions, but desire to claim broadly any equivalents thereof which may suggest themselves to those skilled in the art.

lVhat I claim and desire to secure by Letters Patent of the United States is:
